Howard Schoenfield! Possibly the greatest player off all time that never happened. If he hadn't had the family/psychiatric/drug problems that he had, Connors, Borg and McEnroe may have won fewer majors than they did win. I have no idea where he is now.

Here's a KnightRidder/Tribune newspaper article on Howard Schoenfield from 1996 entitled: "He was as good as McEnroe, but it didn't help him beat mental illness, drug use." (You have to answer some survey questions to see the full article).

"Schoenfield lives in what used to be a bed and breakfast in Hialeah. Now it is a halfway house offering supervised living for adults with mental problems. The building has a bright coat of orange paint and an equally optimistic name: Happy Home.
